Business first: After finishing "Rats in the Ruins," I get a completion message every turn prompting me to choose my reward (cash money,the doom club, or diplomatic capital). If I choose the doom club, then the dialog pops up again instantly. Choosing the other two options makes the dialog pop up every turn. I actually *do get* whatever reward the button says, so I have quite a few doom clubs.
Gushing: WOW. First of all, on normal, the AI kicks the crap out of me. The game also looks a *lot* better. Seriously, FE0.85 plays, looks, feels, and is a lot better than I imagine WOM 2.0 would be. Well done.
Update: I also get the prompt after finishing any subsequent battle later, or after quitting and reloading the saved game. Suffice to say, I'll be starting a new one. Also, there is one semi-irregular thing about this quest: my army killed the rats, but was then ground into tiny pieces by a hoarder spider army. I completed the quest after respawning. Also, the rat's tail, which I think you have to turn in at the end, is no longer in my inventory.
